How much CPU I need to run idle meteor server?

How much CPU I need to run idle meteor server? I noticed after started a meteor app even without traffic, cpu load going up considerably. Is this only my app issue or normal situation?

Most of my servers stay idle around 1-2%. If the CPU increases over time that’s a sign of a ‘cpu leak’, meaning there’s a compounding of processes. If it stays constant that’s just regular cpu usage. What is the cpu usage% for you?
